Podcast 64: Brain Freeze

Happy Holidays, everyone.  We taped this a few weeks ago, but Shrinky Podcasts always make for good holiday chatter.   Today we talk about 
1) Brain Freeze-- inspired by a Well article in the NYTimes for 11/10 on Rick Perry's Brain Freeze.  You'll note that in this podcast, Dinah reads Roy's mind, and no has brain freeze from eating cold ice cream.  We kind of ramble, and so what else is new?  We talk about memory and attention and learning and Dinah explains why men don't take out the garbage during football games.  Clink talks about the scientific phenomena of "brain overload."

2) Siri-- ah, we did this podcast right after I got my new iPhone and it was new and exciting and I was working on an article on Siri and the healthy.  We ask Siri where we can buy a duck and when the world will end.  Apparently we have 5 billion years.  And Sigourney Weaver was 62 years, 1 month, and 5 days old at the time we recorded.


3) Prison Food-- inspired by a lawsuit in which a prisoner contends that the soy-based food being served in prison is 'cruel and unusual punishment' which caused him cramps. Clink talks about how prison food is handled.  She also talks about nutrient rich Nutraloaf that can be eaten without utensils and she discusses an NPR story which includes the recipe for anyone who would like to try nutraloaf. 


If you'd like to try it:
Special Management Meal
Yield - Three Loaves

• 6 slices whole wheat bread, finely chopped
• 4 ounces imitation cheddar cheese, finely grated
• 4 ounces raw carrots, finely grated
• 12 ounces spinach, canned, drained
• 2 cups dried Great Northern Beans, soaked,
cooked and drained
• 4 tablespoons vegetable oil
• 6 ounces potato flakes, dehydrated
• 6 ounces tomato paste
• 8 ounces powdered skim milk
• 4 ounces raisins

From Clink: You mispelled nutraloaf. Don't worry, I fixed it. Also, by pure coincidence today's correctional nursing topic on Lorry Schoenley's Blogtalk radio show was all about managing food allergies in corrections. For those of you who want to know what happens to inmates with peanut allergies, here it is directly from someone in the know.

Suicide, Brains, and Football

In yesterday's New York Times, Alan Schwarz wrote about the tragic suicide of football player Dave Duerson this past week. Schwarz notes that prior to shooting himself, Duerson texted family members that he wanted his brain examined for Chronic Traumatic Encephalopathy, a condition we've discussed before in our post Brains, Behavior, and Football.

Schwarz writes:

Doctors, N.F.L. officials and even many players denied or discredited the links between football and such brain damage for months or even years. The roughly 20 cases of C.T.E. that have been identified by groups at Boston University and West Virginia University were almost always men who had died — most with significant emotional or cognitive problems — with no knowledge of the disease. Now, for the first time he knows of, Stern said, a former player has killed himself with the specific request that his brain be examined.

I'm left to wonder, did this former football player have this problem? Sometimes depression alone causes memory problems and sometimes people with depression worry that they have Alzheimer's disease, or any number of other illnesses for that matter. Treating the depression may help the memory problems, and may alleviate the fears of other illnesses. And we don't know much about the Chronic Traumatic Encephelopathy induced by repeated head injuries: is the course of the dementia altered by early intervention with medications? Does the depression respond to the usual treatments for mood disorders? Could Mr. Duerson have been saved, at least for a while?

Here's an article on the treatment of chronic brain injury with hyperbaric oxygen in animal models:

And here's an emedicine article on treatments for repetitive brain injuries (not necessarily specific to CTE) with medicine recommendations, but no mention of antidepressants or medicines to slow the course of dementia:

Here's a medscape article on CTE and dementia:
http://www.alzheimersreadingroom.com/2010/08/causes-of-dementia-chronic-traumatic.html

And, finally, here's a shout out to my friend and med school classmate Robert Morrison, M.D., Ph.D. whose paper for our public health class was published in JAMA back in 1986 as a state of the art review of boxing and brain injury: http://jama.ama-assn.org/content/255/18/2475.short

Is it worth it in the name of sports?

Could I ask a huge favor of the next football player who considers suicide? Instead of completing the act, could you have your depression treated and then write about the results? It would be an enormous contribution. Sure, it would be an anecdote, and not a controlled trial, but perhaps it would add something to the field. And we'd be happy to publish your story here on Shrink Rap.

My heart goes out to the family of Dave Duerson.

Meditation: Does it Do Anything?

Meditation sounds like a great idea from the perspective of a healthy: anything that calms and focuses the mind is a good thing (and without pharmaceuticals: even better!).

Personally, I tried Transcendental Meditation as a kid...more to do with my mother than with me...and found it to be boring. I have trouble keeping my thoughts still. They wander to what I want for dinner and should I write about this on Shrink Rap and will Clink and Victor ever eat crabcakes with me again and did I remember to give my last patient informed consent and a zillion other things. Holding my thoughts still is work.

The New York Times Well blog has an article on Meditation and Brain Changes. In "How Meditation May Change the Brain," Sindya N. Bhanoo writes:

The researchers report that those who meditated for about 30 minutes a day for eight weeks had measurable changes in gray-matter density in parts of the brain associated with memory, sense of self, empathy and stress. The findings will appear in the Jan. 30 issue of Psychiatry Research: Neuroimaging.

M.R.I. brain scans taken before and after the participants’ meditation regimen found increased gray matter in the hippocampus, an area important for learning and memory. The images also showed a reduction of gray matter in the amygdala, a region connected to anxiety and stress. A control group that did not practice meditation showed no such changes.

-------Lower stress, lower blood pressure, higher empathy.... I may have to give meditation another try. The cartoon above, by the way, shows Roy leading a meditation session. Now there's a thought.
